Are earlier years of data available for the TEDS-Discharges series?

The earliest year available for TEDS-D is the 2006 file. The Substance Abuse and Mental Health Services Administration (SAMHSA) has no plans for making earlier years of TEDS-D available at this time.

When will the next year of data be available for NSDUH?

The NSDUH public-use file (PUF) is typically released for the preceding year by the end of November or beginning of December.

The NSDUH Restricted-use Data Analysis (R-DAS) file is typically available one to two months following the release of the PUF.

Who is the sponsor for NSDUH?

The Center for Behavioral Health Statistics and Quality (CBHSQ, formerly the Office of Applied Studies), Substance Abuse and Mental Health Services Administration (SAMHSA), Department of Health and Human Services (HHS).

How do I get the TEDS-A Concatenated file?

The TEDS-A concatenated data file is now available for download. This public-use file is provided in an ASCII rectangular format with SPSS and SAS data definition statements. A SPSS System and ASCII tab-delimited files are also available. Please note that because of the size of the data file normally available Stata files and the SAS Transport s file were unable to be produced.

If you are unable to download the file in one of the available formats, SAMHDA can provide you with the file. You can obtain the entire data set or select a subset of cases and/or variables. We can make the files available to you through a special Web link where you can access them directly. This is the quickest and easiest way for you to get the data you request. However, we can send you a CD of the files as well.

Please email us the following information at samhda-support@icpsr.umich.edu

1. Data File Delimiter (choose one of the following):

   None -- the preferred delimiter for analyzing the data using SAS, SPSS, or Stata.
   Blank -- one of two delimiters for using Excel, Access, or other similar software package.
   Comma -- another delimiter for using Excel, Access, or other similar software package.

2. Type of setup file(s) (choose one or more of the following):

   SAS
   SPSS
   Stata
   DDI (XML)
   SDA (DDL)

3. Cases: Please indicate whether you desire all cases or a subset of cases. One common example of a subset would be to request only those cases for a given state. You may also request more than one filter to define a subset (e.g., males in the 12-14 year old age group). Please refer to the TEDS codebook when considering filters. Please note that some variables, such as age, are categorized and therefore only allow for certain specific age ranges.

4. Variables: Please indicate whether you desire all variables or a subset of variables. If you request a subset of variables, please refer to the TEDS codebook when choosing variables for the subset. We prefer that you make your requests using Variable Groups (e.g., CLIENT CHARACTERISTICS, SUBSTANCES OF ABUSE: ORIGINAL VARIABLES, etc.).

As soon as we get this information from you, we will begin to process your request. We will email you instructions on how to retrieve the file from the Web site.

When will the next year of data be available for MTF?

The MTF data files are released after the annual report is published, which is at the end of October in the year following the data collection. For example, the 2009 data files were released in October 2010.

Important note about using the RECODE or COMPUTE online analysis features for TEDS-A, Concatenated

This FAQ applies to data users who are creating new variables using the RECODE or COMPUTE functions in the SAMHDA online analysis system (SDA). Due to the large number of cases involved in the TEDS-A Concatenated data set, it may take up to 30 minutes for SDA to complete a RECODE or COMPUTE command. The system will use a new variable (created using RECODE or COMPUTE functions) in an analysis even before the variable is completely created; thus, users are requested to pay close attention to analytic results that use a newly created variable to make sure that enough time has elapsed and the new variable has been completely created. It is recommended that users wait for approximately 30 minutes before using newly created variable in analyses.

When running either RECODE or COMPUTE, you may encounter one of the following: (1) the screen turns blank and the status indicator in your browser says "Done" or (2) the server "times out." If these problems occur, SDA will still continue to process your request, although it may take 30 minutes or more to complete.
